McCartney last played Seattle in 2013 and was joined on stage by the surviving members of Nirvana — Krist Novoselic, Dave Grohl and Pat Smear — for a rousing encore that included the song “Cut Me Some Slack.”

McCartney commented to the press on Wednesday about the passing of Beatles producer George Martin, who died Tuesday at the age of 90.

“If anyone earned the title of the fifth Beatle it was George,” Paul McCartney said.
